Answer:

The probability of selecting a solid black marbles both times;

P = 9/100

Attached is the completed question;

Step-by-step explanation:

Number of solid black marbles = 3

Total number of marbles = 10

The probability of selecting a solid black marble;

P1 = 3/10

With the assumption that the marbles are replaced before next selection.

The probability of selecting a solid black marbles both times;

P = P1 × P1 = 3/10 × 3/10 = 9/100

P = 9/100

equation in slope-intercept form is:

y=9x+7

Step-by-step explanation:

The general form of slope-intercept form is:

y=mx+b

where m is the slope and b is the y-intercept

In the question we are given slope m=9 and a point(0,7)

We will find b i.e y-intercept

y=mx+b\\7=9(0)+b\\7=0+b\\b=7

So, value of b=7 and value of slope m=9

So, equation in slope-intercept form is:

y=9x+7
